To a/ZZ whom t may concern.-

Be it known that I, PIERRE DANSEREAU, a subject of the King of GreatBritain, residing in the city and district of Montreal, Province ofQuebec,`Ca`nada, have invented certain new and useful Improvements inAxle-Nuts; and I do Vhereby declare that the following is a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and nsethe same.

Myinvention relates toaXle-nuts; and my object is to provide a simplearrangement for Y retaining a wagon-wheel in position upon its spindleand to provide for adjusting the retaining-nut in a simple manner, so asto take up the wear which takes place at this part.

The invention consists in the construction and combination of parts tobe more fully described hereinafter, and definitely set forth in theclaim.

In the drawings, which fully illustrate my invention, Figure 1 is aperspective View representing the sleeve of a wheel-hub, a portion ofwhich has been broken away, as illustrated. Fig. 2 is aperspective-showing a collar used in connecting the parts. Fig. 3represents, also in perspective, the hub-nut. Fig. 4 represents inperspective a washer. Fig. 5, which is also a perspective, representsthe cap-nut. Fig. 6 represents in perspective a portion of the axle,showing the spindle with the sleeve, dac., removed. Fig. 7 is a verticallongitudinal section through the spindle and hub-sleeve, showing all theparts in their assembled relation.

It should. appear that Figs. 1 to 5 of the drawings represent the partssubstantiallyin the order in which they are applied to the spindle.

Throughout the drawings and specification the same numerals of referenceindicate like parts. I

Referring more particularly t'o the parts, 10 represents an axleprovided with the usual shoulder l1, beyond which is formed the spindlel2, which spindle has a reduced eX- tension 13, which is provided withthreads 14 for a portion of its length, and it should appear that thisextension is mutilated or cut away so as to have al flat face 15. Anoilgroove 16 may be formed in the lateral surface of the spindle 12, asindicated. It should appear that adjacent to the extension 13 thespindle 12 is formed into an annular shoulder 17. A hub-sleeve 1S isadapted to be applied to the said spindle in the manner indicated inFig. 7. It should appear that this sleeve is of a common form,having aninner bore 19 of substantially the diameter of the spindle 12 and anenlarged bore or mouth 20, provided with an internal thread, asindicated, the enlarged bore 2O being connected with the reduced bore bya conical shoulder 21, as shown. After this sleeve 18 hasA been appliedto the spindle in the manner shown a collar 22 is applied to the reducedextension 1,3. It should appear that this collar comprises a body 23 ofsubstantially cylindrical form having an incomplete bore 24, whereby aflat face 25 is formed. This collar has a head 26 of enlarged diameterand a conical shoulder 27, as shown. It should be understood that thiscollar is applied to the reduced eX- tremity of the spindle in themanner shown in Fig. 7, so that the flat face 25 rests upon the fiatface 15, the inner extremity of the body 23 resting adjacent to theaforesaid shoulder 17. When so applied, the conical 'face 27 abutsagainst the conical shoulder 21 aforesaid, and this collar from thisarrangement affords means for retaining the sleeve 18 in position. Thehub-nut 28 is then applied, being received by the threads 14 aforesaid,and, as will be readily understood, it is eX- pected to maintain thecollar 22 in position. It consists, substantially, of a body 29,preferably of hexagonal form, having an annular shoulder or head 30,providing an inner face 31, which is adapted to rest against the outerface of the collar 22, as indicated. The lateral faces 32 ofthis nut areprovided with elongated openings or recesses 33, which are disposedlongitudinally with reference to the axis of the nut and which extendthrough to the bore 34 of the nut at the outer face 40 thereof. Theseopenings or recesses 33 are for the purpose of effecting an adjustmentof the nut and for retaining the same in different positions. For thispurpose they coperate with a small split pin 35, which is insorted in atransverse opening 36,which passes diametrically through the threadedextension 13, as illustrated most clearly in Figs. 6 and IOO 7. As willbe readily' understood, this pin is adapted to pass through a pair ofthe diametrically opposite openings. Evidently to effect an adjustmentof the nut it is necessary only to remove the pin and to turn the nut ineither direction to the desired amount, bringing a second pair of theopenings 33 into alinement with the opening 36 and replacing the pin asbefore. After these parts have been assembled in the manner described acap-nut 37 may be screwed into the threaded bore 20 of the hub-sleeve18, the Washer 38 being first applied to the extremity of the sleeve, asindicated. It should appear that this cap-nut 37 has an internal bore orchamber 39,Which receives the aforesaid nut 2S and the threadedextension 13 of the spindle. i y It should appearl that in the mannerdescribed a very simple arrangement is provided for maintaining the hubin position and at the same time enabling necessary adjustments to bequickly made when desired. Evidently the cap-nut 37 affords means forpreventing any possibility of the accidental removal or displacement ofthe split pin 35 unless the cap-nut 37 has been iirst removed.

Upon reference to Figs. 6 and 7 it will be seen that the spindle 12 isformed with an annular groove l5 at a point about midway the length ofthe iiattened portion 15, and the collar 22 is so disposed when inposition lthat the head 26 thereof extends partially across said groove,as seen in Fig. 7, the collar not fitting snugly to the spindle, as` isshown in said figure, thus permitting the lubricant to readily nd accessto all parts of the journal and to the hub-nut and the threads on thespindle with which said hub-nut is engaged.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

The combination with the spindle having reduced extension withscrew-threads, fiattened portion, annular groove intersected by saidflattened portion, shoulder and transverse opening, of a sleeveinclosing said spindle and having enlarged mouth with internal threads,and a conical shoulder, a collar having a bore with flattened faceconforming to the flattened portion of said extension, an enlarged headextending partially across said conical shoulder of said sleeve, acap-nut threaded upon the threaded portion of said extension and havinglateral faces with longitudinally-disposed openings, a spring-pin passedthrough said openings and through the opening in said extension, awasher bearing against the outer end of said sleeve and a cap-nut havingthreaded extension engaging the internal threads of the mouth of saidsleeve, and a flange engaging` the outer face of said washer, the partsall being arranged, constructed and operating, substantially as shownand described.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
